ILLUMINATING-TORCH.

SPECIFICATION forming part of Letters Patent No. 313,819, dated November8, 1898,

Application filed July 25, 1898. Serial No. 686,793. (No model.)

To all whom it may concern:

Be it known that I, GEORGE KELLY, a citizen of the United States,residing at Mineral Point, in the county of Iowa and State ofW'isconsin, have invented certain new and useful Improvements inIlluminating-Torches; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to illuminatingtorches; and the object is tosimplify and improve the construction and increase the illuminatingpower without adding to the cost of manufacture.

To this end the invention consists in the construction, combination, andarrangement of the device, as will be hereinafter more fully described,and particularly pointed out in the claims.

The accompanying drawings show my invention in the best form now knownto me; but many changes in the details might be made within the skill ofa good mechanic without departing from the spirit of my invention as setforth in the claims at the end of this specification.

The same reference characters indicate the same parts of the invention.

Figure 1 is a vertical section of a torch embodying my invention. Fig. 2is a transverse section on the line 2 2. Figs. 3, 4, and 5 showdifferent forms of caps. Fig. 6 shows a stationary torch provided withmultiple burners. Fig. 7 is a similar form of burner forheatingpurposes.

1 represents the reservoir, and 2 a diagonal foraminous tube extendingfrom within a short distance of the bottom of the reservoir to a pointbeyond the wall, and 3 denotes a tube which encompasses the projectingend of the tube 2, and its outer end is in turn encompassed by aconcentric longitudinallycorrugated cap or sleeve 4. The tubes 2 and 3are loosely packed with any suitable noncombustible fiber-such asmineral wool, asbestos, or the like-which becomes saturated with the oilin the reservoir through the foraminous tube 2, which is then conductedby capillary attraction to the open end of the tube 3, where it isignited to produce the illuminating-flame. As this end of the tube 3 andencompassing cap 4 become heated a part of the oil becomes vaporized andthe heat causes a current of air to flow through the longitudinalgrooves in the sleeve 4. The air thus heated, mixing with the vapor fromthe end of the tube 3, is carried into the flameto give greaterbrilliancy to the light.

In Fig. 3 I have shown the cap or sleeve 6o formed of cast-iron,cylindrical in form, and provided on its inner face with a series of1011 gitudina-l parallel grooves to form passages for the he ed air.

In Fig.3 he outer end of the tube4 is cor rugated or fluted and thesleeve 4 is a plain cylinder which encompasses said corrugated end, andin Fig. 5 both the tube and the sleeve are plain cylinders, and a seriesof longitudi nal parallel ribs a are inserted between the tube andsleeve to form the air-passages.

In Fig. 6 the reservoir 1 is connected to the tube 3 by a valved pipefor feeding the oil to the foraminous tubes 2 and 2 2. 3 3 representlateral burner-tubes which encompass the corresponding foraminous tubes2 2, and any suitable number of these maybe radially arranged around thecentral tube 3 to correspond to the brilliancy of the light required.

In Fig. 7 I have shown the outer end of the burner-tube 3, where it isencompassed by the sleeve or cap 4, formed with a series of lateralorifices, so that the gaseous vapor may combine or intermiX with the airin the sleeve,

and thus add the mixed air and gas or vapor combination with alongitudinal fluted concentric sleeve encompassing said Wick-tube, andhaving its opposite ends open to the atmosphere, substantially as shownand de- 5 scribed.

2. A torch provided with a wick-tube, in combination with alongitudinally-fluted concentric sleeve encompassing said wick-tube andhaving its outer end serrated, substan- Ioo tially as shown anddescribed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
